Definitions
- the present invention relates to compounds of general formula I
- E 2 is bound either to the 8 or 9 position of the perylene skeleton and is identical to E 1 ,
- W a bridging C2 or C3 moiety which may be substituted by one or more alkyl
- R 3 identical or different radicals hydrogen, alkyl, cycloalkyl, aryl, hetaryl, alkoxy,
- Y oxygen or NR 12 and hydrogen, alkyl, cycloalkyl, aryl or hetaryl,
- A is -COOM, -SO3M or -PO3M
- M hydrogen, alkali metal cation or [NR ' ] 4+ , hydrogen or alkyl, where the radicals R ' may be identical or different, and
- Lg leaving group m 0 or 1 , where in the case of m equal 1 the one Lg is bound either to the 8 or 9
- R 1 , R 2 independently of each other a moiety of formula Ilia
- the direct conversion of solar energy to electrical energy in solar cells is based on the internal photoeffect of a semiconductor material, i.e. the generation of electron-hole pairs by absorption of photons and the separation of the negative and positive charge carriers at a p-n junction or a Schottky contact.
- the photovoltage thus generated can bring about a photocurrent in an external circuit, through which the solar cell delivers its power.
- Thin layers or films of metal oxides are known to constitute inexpensive solid semiconductor materials (n-semiconductors), but their absorption, owing to large band gaps, is typically not within the visible region of the electromagnetic spectrum.
- the metal oxides therefore have to be combined with a photosensitizer which absorbs in the wavelength range of sunlight, i.e. at from 300 to 2000 nm, and, in the electronically excited state, injects electrons into the conduction band of the semiconductor. With the aid of a redox system which is used additionally in the cell and is reduced at the counterelectrode, electrons are recycled to the sensitizer which is thus regenerated.
- DSCs Dye-sensitized solar cells which are based on titanium dioxide as the semiconductor material are described, for example, in US-A-4 927 721 , Nature 353, p. 737-740 (1991 ) and US- A-5 350 644, and also Nature 395, p. 583-585 (1998) and EP-A-1 176 646.
- These solar cells comprise monomolecular films of transition metal complexes, especially ruthenium complexes, which are bonded to the titanium dioxide layer via acid groups, as sensitizers and iodine/iodide redox systems present in dissolved form or amorphous organic p-conductors based on spirobifluorenes.
- metal-free organic dyes have attracted increasing attention as they do not contain any toxic or costly metal and their properties are easily tuned by facile structural modification.
- they generally have much higher extinction coefficients when compared to Ru(ll) polypyridyls, making them excellent for use in solid state DSCs in combination with hole transporting materials such as P3HT as shown, for example, by G. K. Mor, S. Kim, M. Paulose, O. K. Varghese, K. Shankar, J. Basham and C. A. Grimes, Nano Lett., 2009, 9, 4250, or spiro-MeOTAD as shown, for example, by H. J. Snaith, A. J. Moule, C. Klein, K.
